7 Claims. (Cl. 131-4) This invention relates to a cigarette having anoncombustible wrapper and more particularly to a cigarette having aform-retaining noncombustible wrapper adapted to hold the ash thereinuntil the tobacco in the wrapper is consumed. Said wrapper is alsoadapted to provide an immediate source of air to support the burning ofthe tobacco therein and to provide ventilation to cool the hot gases orair therein so that the same may be substantially cooled before beingdrawn into the mouth of the smoker.

It is an object of this invention to provide a cigarette having awrapper made of a noncombustible sheet material adapted to become porousor apertured when affected by the burning of tobacco therein whereby animmediate source of air is present to support the combustion of thetobacco in said wrapper.

It is another object of this invention to provide a cigarette having awrapper made of a form-retaining noncombustible sheet material adaptedto become apertured when affected by the coals of the tobacco burningtherein whereby said porous or apertured condition moves continuouslycloser to the mouth end of the cigarette as the same is consumed and theash resulting from the burning tobacco is retained in said wrapper.

It is more specifically an object of this invention to provide acigarette having a wrapper made of a formretaining non-combustible sheetmaterial adapted to have a multiplicity of apertures therein spacedcircumferentially and longitudinally of said wrapper, a readilycombustible material filling said apertures, the outer end of saidwrapper having an apertured closure, whereby the tobacco in the wrapperis ignited at said closed end and as the tobacco burns towards the mouthend of the cigarette the material filling said apertures is consumed bythe burning coals of the tobacco, thereby providing an immediate sourceof air to support the combustion of said tobacco and providing a meansof ventilation for the hot air and gases produced in said wrapperwhereby the same may be substantially cooled before being drawn into themouth of the smoker.

It is still another object of this invention to provide a novelcigarette and method of making the same.

It is an additional object of this invention to provide a novelcigarette wrapper and method of making the same.

These and other objects and advantages of the invention will be fullyset forth in the followingdescription made in connection with theaccompanying drawings in which like reference characters refer tosimilar parts throughout the several views and in which:

2,754,828 Patented July 17, 1956 Referring to the drawings, a cigarette10 is shown. With reference to Fig. 3, tobacco 11 is shown which is usedas av filler in forming said cigarette. A wrapper 12 is shown in Fig. 5in a developed view and in Fig. 1 as having an elongated tubular formenclosing said tobacco 11 to form cigarette 10. Said wrapper may be madeof any suitable noncombustible sheet material but in the embodiment ofthe invention as illustrated, said sheet material is shown to be a thinsheet of asbestos paper. Said wrapper is adapted to become porous orapertured when and as affected by the heat of the tobacco burningtherein. In the embodiment of the invention as illustrated, said wrapperis shown as having a multiplicity of apertures 12a. Referring to Fig. 1,said apertures are shown as being circurhferentially and longitudinallyspaced in said wrapper. As shown in Fig. 3, said apertures are shownspaced to form a pattern and as here illustrated, a specific pattern isshown. Disposed in said apertures and filling the same is a readilycombustible material 13, and while different materials might be used, inthe embodiment of the invention disclosed and in practice said materialhas been cellulose fibers. The side edge portions 12b of said wrapperoverlap and said edge portions are secured together by a suitableadhesive. Covering the outer end of said cigarette is a disc-likeclosure 14 made of some suitable noncombustible material which could bethe same as that of said wrapper. Said closure has a multiplicity ofopenings 14a therein. Flap portions 12c are provided at the outer endportion of said wrapper 12 and the same are turned inwardly to be atright angles to said wrapper. Said end piece is secured to the outersides of said flaps preferably by an adhesive.

In operation and in carrying out the method of the invention, a wrapper12 is formed of a sheet of noncombustible material and said wrapper issubstantially rectangular.

Said wrapper is then perforated with a multiplicity of small holes 12a.Said holes are in spaced relationand may be arranged as shown in Fig. 5to form characters such as letters. Said holes are then filled with areadily combustible material 13.

Said wrapper 12 is then disposed around a tobacco filler 11 to form asubstantially cylindrical cigarette. The side portions of the wrapperare overlapped and are secured by a suitable adhesive.

Said wrapper has flap portions at one end and the same are turnedinwardly. A disc-like closure 14 is placed against said flaps and oversaid end of said cigarette. Said closure is secured to said flapportions by a suitable adhesive. This closes one end of said cigarette.Said closure 14 is perforated to have a plurality of small openingstherein.

The cigarette is lighted at the outer end and air is drawn inwardlythrough said openings 14a in the end closure 14 of said wrapper, whichopenings provide a source of air and permit a sufiicient draft to becaused for igniting the tobacco in the cigarette. As the tobacco isburned, the combustible filler material 13 in the apertures immediatelyadjacent the burning tobacco will be consumed and thus said apertures12a will be opened. Said apertures will thus provide an immediate sourceof air to support the burning of the tobacco. Also when the smoker drawson the cigarette, air will be drawn through the apertures adjacent theburning portion of the cigarette and also through those about the usedportion of the cigarette and said air entering into said wrapper willserve to reduce the heat generated within the wrapper and said air has aconsiderable cooling effect on the fumes that are drawn into the smokersmouth by the action of smoking. During the interval of time when thesmoker is not drawing inwardly on the cigarette the heated air withinthe wrapper will escape through the opened apertures in the upperportion of the Wrapper and the incoming supply of air will enter throughthe opened apertures in the lower portion of the wrapper. Thus there isa constant change of air within the portion of thewrapper in which thetobacco is being and has already been consumed. As the tobacco in thewrapper is consumed, the resulting ash will be retained within thewrapper and the perforations will be of such size that said ash will notescape therethrough. The ash is substantially porous and it will notobstruct ventilation of the wrapper. Said wrapper is adapted to beshape-retaining throughout the entire period of time during which thecigarette is used. Hence the dropping of ashes is entirely eliminatedand the smoker need have no concern regarding the cigarette or thedisposal of any ash until all of the tobacco in the wrapper has beenconsumed. When this has been done the wrapper may be disposed of alongwith the ash which has been retained therein. As said cigarette is beingconsumed, said filled apertures in said wrapper are opened from theouter end of said cigarette towards the mouth end of said cigarette.Hence as shown in the embodiment of the invention as illustrated in Fig.5, said apertures may be spaced so that when they are opened, saidopenings will form a specific pattern, and as here illustrated, theletters ABC are formed.

Thus it is seen that I have provided a very useful invention in acigarette and method of making the same. The cigarette has thesubstantial utility of retaining therein the ash resulting from thesmoking of a cigarette. This important function obviates the nuisanceand the danger of damage and fire resulting from dropping ashes andmakes unnecessary any attention being given the cigarette until it hasbeen entirely consumed. This wrapper has been found to be very eflicientand entirely satisfactory in actual use.

It will of course be understood that various changes may be made in theform, details, arrangement and proportions of the parts, Withoutdeparting from the scope of applicants invention, which generallystated, consists in a device capable of carrying out the objects aboveset forth, in the parts and combinations of parts disclosed and definedin the appended claims.
